Table 1. Details of the three superlattice systems investigated in this work.

They are based on the FCC-crystal lattice structure and are composed of: (S1) two intercalated crystalline layers (A and B) formed by point particles with different masses m_A and m_B; (S2) ordered crystalline layers intercalated to mass-disordered alloy layers; and (S3) identical crystalline layers with modified (weakened compared to those intra-layers) interactions across the interfaces. The control parameters are the mass ratio m_B/m_A in S1, the mass ratio m_B2/m_B1 of the disordered alloy layer in S2, and the energy scale ε_AB of the interactions across the interfaces in S3. Number density and temperature were fixed to the values (corresponding to a lattice constant a = 1.58) and T = 10⁻², respectively. The quantities presented in the table are defined in the main text. In the last column we refer to the figure containing the data relative to the indicated system. Additional details about the investigated superlattices and parameters used are given in the Methods section.
